Where surrounded by north tyneside might a charity adopt toddler equipment ie baths,highchairs etc shops not interested?
Try the PDSA, if you have one near you. I hold recently donated lots of stuff there, I asked whether they took equipment such as large chairs, rocker chairs, walkers etc. They said they did no problem - if they couldn't sell them within the shop in my town, they could be transferred to another branch. So, they may be a good bet.
Or, another road may be to put them on Freecycle - there will probably be a group near you. It is constituent of Yahoo groups, so look in there and see if nearby is a group you could join.
